;;; (Latoocarfian a b c d)

;;; This is a function given in Clifford Pickover's book Chaos In
;;; Wonderland, pg 26.  The function has four parameters a, b, c, and
;;; d.  The function is:
 
;;; xnew = sin(y * b) + c * sin(x * b); 
;;; ynew = sin(x * a) + d * sin(y * a); 
;;; x = xnew; 
;;; y = ynew; 
;;; output = x; 
 
;;; According to Pickover, parameters a and b should be in the range
;;; from -3 to +3, and parameters c and d should be in the range from
;;; 0.5 to 1.5.  The function can, depending on the parameters given,
;;; give continuous chaotic output, converge to a single value
;;; (silence) or oscillate in a cycle (tone).  This UGen is
;;; experimental and not optimized currently, so is rather hoggish of
;;; CPU.
